I am having probl w/word problems.
A kitchen floor is covered w/altern black and white tiles. Ech tile is a 12 inch square. If the kitchen meas 10'x10' how many black tiles are on the floor?
Is this right
10 x 10= 100'
100' x12= 1200"
1200 divided by 12= 100
100 divided by 2= 50 black tiles

Your answer looks correct to me, but I don't see the relevance of the two intermediate steps. Each tile is one foot square; you've got 10x10=100 of them in a square, so it looks like a 10x10 chessboard. Half of those 100 squares will be black. (Just one thing: 10 feet x 10 feet = 100 square feet, not 100 feet, which is what 100' means.)
